SS Hot Rolled Coil & Plates
Hot rolling primarily involves deforming the slab / bloom at high temperature & roll
pressure - The rolling temperatures vary from 900˚C to 1200°C, which is above the
recrystallization temperature for most stainless steels.
The material runs through a series of roll with predetermined roll gaps, pressures, and
speeds to achieve its finished dimensions while being at high temperatures.
High finishing temperature ensures the production of a uniform rolled product, increases
the ability of the material to undergo thickness reductions up to 98%, and at the same
time, prevents the possibility of unwanted strain hardening. After hot rolling, the long
and thin sheets are spun into coils and left to cool, these are called Hot Rolled
coils.
